Integrated pumps and valves make up an essential part of most microfluidic devices and produce increased control in the device. Some existing micro-pumps and valves utilized in microfluidics involve electrical, pneumatic, and thermal actuation. However, electrical micro-pumps and valves generally entail a complicated and expensive fabrication process, and are limited to samples free of any ions...

The spin dynamics of the ferromagnetic pinned layer of ferro-antiferromagnetic coupled NiFe/MnNi bilayers is investigated in a broad frequency range (30 MHz-6 GHz). A phenomenological model based on the Landau-Lifshitz equation for the complex permeability of the F/AF bilayer is proposed. The experimental results are compared to theoretical predictions.

The present article analyzes aspects of the intellectual trajectory of Maria Cecília Ferro Donnangelo and her principal works. The text emphasizes the innovating and pioneer role her work played in the first moments of social sciences in the field of health in the mid sixties, occurring just together with changes in medical education and medical practice in Brazil.

In a double-blind trial the response to treatment with Ferro-Gradume (a slow-release preparation of ferrous sulphate) has been compared in the same individuals with the response to ferrous fumarate in a single daily dose regimen using a similar dose of iron. No significant difference was found in the therapeutic response or in the incidence of side-effects between the two preparations.

The temperature dependence of the thickness of thick free-standing films is studied using a high-resolution film thickness measurement technique. A small discontinuity in the temperature dependence of the smectic layer thickness at every phase transition between ferro-, ferri-, and antiferroelectric phases is observed. We show that the major contribution to it arises from a change in the smecti...

Throughout the development of syntactic theory, it has been widely assumed that sentence structures are represented as a certain type of graph, called a tree. On the basis of a variety of diagnostics, the words in a sentence have been taken to clump together to form hierarchically organized subgroupings, called constituents. Thus, the sentence every child ate some cabbage is assumed to have the...
